Question

What is the role of desorption in the process of catalysis?

Answer 1

Catalysts are the chemical reagents not involved in the chemical reaction but enhance the rate of the chemical reaction by providing a suitable surface to the chemicals to react with other and then to convert into products.

Complete answer:
- In the question it is asked to write about the role of the desorption process in the process of catalysis.
- First, we should know about the process of catalysis.
- Catalysis is a process in which the chemical reactants are going to convert into products with the help of the catalyst.
- The catalyst is going to provide a clear surface to the reactants.
- So, that the chemicals are going to occupy the surface of the catalyst.
- The reactants occupy the catalyst surface and they start to react with each other.
- After the chemical reaction on the surface of the catalyst the reactants are going to convert into products.
- The formed products must vacate the place from the surface of the catalyst in the process of the catalysis.
- The process of removing the products from the catalyst surface is called desorption.
- After desorption only the catalyst is going to participate again in the process of catalysis.

Note:
A lot of chemical reactions like hydrogenation of alkenes nothing but the reduction is going to occur on the surface of the catalyst in the process of catalysis. At the time of preparation of ammonia through Haber’s process there is a need for a catalyst.
